I know this is a sensitive topic for some (converting a Coupe to a Fastback). In no way do I mean to offend anyone.
There are a few members here that don't care much for conversions and are vocal about it (three in particular come to mind) and each is a well regarded member of VMF. Know however that their opinion of coupe to fastback conversions is their problem, not yours.
You will find plenty of interest and support for your build here. Plenty.
